How To Find Out What iPhone You Have

Did you know that Apple Inc has released nearly 29 iPhone models since 2007? And with the hearsay of an iPhone SE 3 and other releases soon, this figure is definitely going to increase. All iPhones run on a mobile operating system which Apple names “iOS”.

A new version of iOS is launched every year, each having more features than the former. Every new iPhone comes out with the latest version of iOS, and the older iPhones usually get a software update to the latest version.

In this vast sea of iPhone models, you might be wondering which iPhone you’ve got. Knowing your model number is essential because certain models may not be compatible with few latest features. For example, the iPhone 11 does not support Touch ID, etc. Also, certain older models may not be able to use the latest updates.

The model number also plays an important role when you put your iPhone for sale Because the Buyer wants to know exactly what they are getting. There can be a lot other reasons why you might need to tell the difference between iPhones. This article is all about how to find out what iPhone you have.

How to Find Out What iPhone you Have Got

Even experienced users can find it hard to identify iPhone apart by sight. This is because Apple updates the iPhone every year, but it doesn’t necessarily make changes in the design. The significant change can be on the inside, such as faster new components, etc.

The easiest way to identify an iPhone was to check the ‘A’ model number on its back, and this article includes the A numbers for every iPhone. But lately Apple does not print ‘A’ numbers. So, for those with recent iPhone models, or who find the number too small to read, there are other methods. You can either check in Settings, or look at the phone’s shape and external features and make an identification.

1. Look in Settings for the Model

Looking in the Settings is the simplest method.

Step 1: Open the Settings app.

Step 2: Tap General.

Step 3: Select About.

Step 4: Among top entries you’ll see “Model Name”, followed by your model. For example, iPhone 12 Pro maybe displayed next to “Model Name”.

Some older iPhones do not show the iPhone model name.

Step 5: Below the “Model Name” is the “Model Number” (also known as the SKU). It’s a combination of letters and numbers that provides a more precise identification as it specifies storage capacity and even color.

The model number is available in both older and new phones.

Step 6: Tap on the SUK to display the A number instead, which can also be used to identify which iPhone model you have.

The settings page also provides information regarding the device’s capacity, which is listed a little further down.

Settings app is extremely helpful when it comes to identifying what iPhone you have. But it is dysfunctional when you’re trying to identify a bricked device or one you can’t unlock. Hence, it would be better to move on to the visual identification chart in the next section.

2. Look on your device

Step 1: Look for identification number printed on the back starting with the letter A, and labelled ‘Model’. For example, “Model A1634”. This is called a number.

If you do not find the A number printed on the back your iPhone is an iPhone 8 or later.

Step 2: On an iPhone 8 or later, remove the SIM tray and look for the A number in the SIM tray slot. The A number is on the upper side—the side with the display.

In both the cases make sure there is bright light overhead. Do not hesitate to get the help of a magnifying glass as the print is small. Once you have got the A number, check it against this list to see which model you’ve got.

Note: There are multiple A numbers for some iPhones referring to various versions for different territories, network standards and so on.
